CONSTRUCTION OF AUTOMOBILE VEHICLES.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed June 23, 1905. Serial No. 266,647.

To all whom it may concern."

Be it known that I, MARoos BIRKIGT, a subject of the King of Spain, anda residentof Barcelona, in Spain, have invented certain new and usefulImprovements in the Construction of Automobile Vehicles, of which thefollowing is a specification.

The present invention relates to improvements in the construction ofautomobile road vehicles for the purpose of supporting the motor andgear box so that their shafts are maintained in true alinement and forobtain, ing an inclosed or sheathed automobile vehicle frame, which iswithout apertures or seams at its outer edge.

The improvements are represented in the annexed drawings in which Figure1 is an elevation and Fig. 2 a plan view of the frame. Fig. 3 is across-section on line 90-40. Fig. 4 shows on the left a front view ofthe frame, and on the right a section on line Y Y. Figs. 5 and 6 areplans of the lower halves of the gear box and engine crank casingrespectively. Fig. 7 is a detail view in section on a larger scaleshowing the connection of the lower halves of the gear box and crankcasing to one another.

The frame consists of two side members A and A of channel steel whichmay be reinforced with wood as illustrated at A Figs. 3 and 4. Theseside members are connected rigidly together at the rear by a cross bar Bof the same material and near the front by a cast crosspiece 0. Thelower flanges of the channel steel side members are extended and bentdownwards as at H towards the lower parts of the motor crank case K andof the gear box D so as to close the space between these and the frame.

For the proper action of the mechanism it is essential that the motorcrank shaft and the change speed shaft should be adjusted and maintainedin alinement. lower half of the motor crank case and the correspondingpart of the gear box are formed so that they can be bolted together,each having an extension K or D The respectively to meet each other anddefine the space in which the clutch is intended to be placed betweenthe motor and the gear box. In forming the contact surfaces of the twoextensions K and D a circular groove 0 (Fig. 4) concentric with theshafts is formed in one of the gear box. These brackets extend to andare bolted directly to the side members A A of the frame by bolts G. Thespaces between said brackets are hermetically closed by the sheet metalportions H H of the frame before referred to, which extend to and arefastened by bolts 1 to flanges K on the crank case and D on the gearbox, and M on the transverse member 0.

I claim as my invention:

1. In an automobile vehicle the combination of a frame comprisingflanged metal side members, a motor crank casing and a gear box,portions integral with the flanges of said side members extended to andbolted to said crank casing and gear box respectively, and bracketsextending to and carried directly by said side members and supportingthe weight of said casing and gear box irrespective of the said portionsof the side members, substantially as described.

2. In an automobile vehicle, the combination of motor crank case andgear box having extended meeting portions, one of said portions having agroove concentric with the motor crank shaft and speed gear shaft, andthe other a rib adapted to engage said groove, said portions adapted tobe bolted together for the purpose described.

In witness whereof I have signed this specification in the presence oftwo witnesses M. BIRKIGT.
